The FM multiplex receiver,and the FM radio,are connected via a main controller,. The main controller,discriminates whether or not the FM radio,is on. In the case that the FM radio,is on, the main controller,controls the tuning of the FM multiplex receiver,lest the tuning frequency of the FM multiplex receiver,should be set to a specified prohibited frequency.
